.17 Mach IV (Hodgdon Data)

.17 Mach IV (Hodgdon Data)

The .17 Mach IV is a cartridge built around speed, and few powder manufacturers complement that philosophy better than Hodgdon. Known for its clean-burning formulations and wide availability, Hodgdon powders help bring out the full potential of this necked-down .221 Fireball case — delivering remarkable velocity with consistency and manageable pressure curves.

Hodgdon data for the .17 Mach IV typically includes favorites like H4198, Benchmark, and Varget. Each provides distinct advantages depending on bullet weight and barrel configuration. For lightweight 20-grain projectiles, Benchmark offers superb metering and velocity performance, while H4198 remains a go-to for reliable ignition and case fill.

In practical application, Hodgdon-based handloads allow the .17 Mach IV to reach speeds over 4,000 FPS, creating a near-laser-flat trajectory — ideal for prairie dogs, ground squirrels, and similar small game at extended distances. Despite the aggressive performance, Hodgdon’s temperature-stable powders ensure reliable results from cold mornings to summer heat.

Shooters often favor Hodgdon’s reloading data for its thorough pressure testing and broad range of safe combinations. With the .17 Mach IV’s small case capacity and high working pressures, this precision is critical. Handloaders benefit from the brand’s long-standing credibility and accessible load recommendations, especially when pushing the limits of high-velocity wildcats.

In short, the pairing of Hodgdon powders and the .17 Mach IV is a natural fit — one that delivers not only raw speed, but repeatable precision shot after shot. For those who want a proven route to maximum varmint-rifle performance, Hodgdon data offers a trusted path forward.
